Ebook database location

[Eugene]

Dear Mr/Ms,

I bought a hardcopy of this book quite a while back and it worked. Now, when I wanted to set up my environment again (Hour 1) I found that JDK 7 is no longer available. So, I think that my copy is outdated. When I looked at the Acknowledgements section, it said that there is a online database with the newest copy [I guess]. I could not find the link to the database so I posted the question here (This is the question). Thank you in advance.
